Im a new user to nico and to rb's. I drive a 91 240 with a rb20, and im experiencing a gargleing noise while driving. Most of the time when im at a high rpms in either 3rd 4th or 5th gear a deep gargle comes out of the exhaust and the car hesitates to get thru it and i lose power. I checked the intercooler pipeing for a boost leak, changed the spark plugs, and even cleaned out the mass air flow sensor. And im still having problems. If anyone has any ideas what it could be please help me out. Thanks its much appreciated.
